What is OAuth?
A standard that lets you log into apps using your existing accounts from Google, Facebook, or other providers
Why It Matters
OAuth makes it easier for users to sign up (no new password to remember) and can be more secure than managing passwords yourself
Real-World Example
Clicking 'Sign in with Google' on a new app instead of creating a new account
“Understanding terms like OAuth matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
